Moon/NEO Key Points!
• EVA dust mitigation similar (NEO may be worse environment)
• Sample acquisition, storage and handling, sample in-situ analysis (triage)
• Teleoperation of robots with real time control by astronauts ‘on scene’
• Both involve highly active mission operations (driving minimal preventative maintenance, prep time for operations, etc.)
• Capabilities for accomplishing similar science task (volatiles, geology, plasma interactions, dust and surface charging, sample acquisition and handling capabilities and techniques
• Ops model – mobile system, get out and work, get back in and go to another location
• Technologies/Capabilities required (ECLSS, thermal shielding, etc.)

Mars/NEO Key Points!
• Important Considerations – Put more attention on synergies in high cost systems – Recognize NEO missions are a critical opportunity for Mars, so this drives a
“design for Mars, use for NEO” approach – Need Strong International Engagement
• Key Points Organized my Mission Phase – Launch
• Important to use similar systems, such as Heavy Lift / Propellant Depots – Transit
• Transit Hab (including power, life support, etc) [*** ISS demonstration opportunity ***] • Cargo/logistics storage capability • Advanced in-space propulsion/EDS • Launch window sensitive capabilities • Crew support/health risk management capabilities • Radiation monitoring and protection capabilities • Nuclear power
Red Text: High cost items
5!NASA Explore NOW • August 10-11, 2010
• Surface Moons – Surface access to Phobos/Deimos – Science Equipment – ISRU – Operations concept similarities Surface – Some Science Equipment (less than moons) Both – Nuclear power – Telerobotics – Autonomous operations (crew/Earth interactions) – Comm/nav/software
• Return – Crew re-entry techniques and capabilities

Moon/NEO Commonalities!
6!NASA Explore NOW • August 10-11, 2010
• Keeping Humans Alive – Radiation Shielding and Mitigation – Dust Mitigation – Vacuum – Life Support System (food, water, and oxygen) – Medical
• Keeping Humans Productive – Dust Mitigation – Robotic Tools – Ability to Sample – Mobility through the Environment – Psychological Aspects
• Autonomous Operations • Sampling
– Sub Surface – Curation (of possible ices) – Training – Acquisition
• Human Training to get best possible samples for an unusual environment • Instrument Deployment

Mars/NEO Commonalities!
• Keeping Humans Alive – Radiation Shielding and Mitigation – Dust Mitigation – Non Breathable Atmosphere – Life Support System (food, water, and oxygen) – Medical
• Keeping Humans Productive – Dust Mitigation – Robotic Tools – Ability to Sample – Mobility through the Environment – Psychological Aspects
• Autonomous Operations • Sampling
– Sub Surface – Curation (of possible ices) – Training – Acquisition
• Human Training to get best possible samples for an unusual environment • Instrument Deployment

Moon/NEO Differences!
• Keeping Humans Alive – Gravity – Ability to Abort Missions
• Keeping Humans Productive – Mobility Scale is different and importance – Gravity
• Autonomous Operations – Potential for Earth based operations
• Sampling – Gravity
9!NASA Explore NOW • August 10-11, 2010
– Keeping Humans Alive • Radiation Shielding and Mitigation (different on the surface of Mars) • Dust Mitigation
– Gravity, Atmospheric Effects are different – Global Dust Storms – Potential Biologically Hazardous)
• Life Support System (food, water, and oxygen) – Atmospheric ISRU – Possible Need for Pre-Position of Resources
• Medical (longer time) – Keeping Humans Productive
• Dust Mitigation (the interactions are different) • Robotic Tools
– Wear and Tear – Many tools would be different
• Ability to Sample (Gravity is different) • Mobility through the Environment (more important on Mars than on NEO, scale is different)
– Planetary Protection • Highgrading of Samples • Forward PP • Back PP
Mars/NEO Differences!
Systems for Human Exploration!
• Life Support • Habitation • EVA Suits & tools • Mobility • Waste management • Thermal management • Power • In-Space propulsion • Launch vehicles & infrastructure • Crew Ascent/Entry vehicle • Robotic support
